Great batteries!

Posted by G. Baker on 3rd Jan 2019

Great batteries!!!! I have about 7 sets of 4 of different variations of these batteries. Some Low Self-Discharge some not. I learned of this brand about 10 years ago and I have been using them ever since. They are GREAT for my external flash for a semi-pro canon camera. They are also great in a recently acquired Whistler TRX-1 Scanner. These batteries are great in everything.

I would also recommend a good external charger for these. Do your research and buy what you need. But, charging in device, or the plug in and forget chargers are usually crap. Buy a good La Crosse or Maha charger to accompany these and you will get a lot of use from them.

High Capacity AA battery

Posted by PScher on 3rd Jan 2019

These are great AA rechargeable batteries. Tested the capacity by draining the battery with a 1.2 volt incandescent bulb @ 250 mA and recharging the battery with a XTAR VC4 charger @ 1A. The battery tested full at 2572 mAh. This was very close to the 2600 maximum mAh rating.

After two months of unused storage, I removed two of the batteries for testing. I recharged both as above and the batteries charged at 411 and 412 mAh. This is about a 16% loss. This amount of drain should only happen after one year. Lowering my rating by one star.

A little pricey, but a great option if optimal voltage is important

Posted by StormJH1 on 3rd Jan 2019

There's a lot of more-affordable 9V rechargable batteries than this, but I purchased the PowerEx 9.6V for a very specific purpose: to use with guitar effects pedals. Inconsistencies in voltage and actual power outputs less than 9V can cause performance issues with electronic audio gear. I had to research this a bit, but most of the "9 volt" rechargeables on the markert actually put out a maximum of 8.4V. If it drops any lower than that, it would very likely cause a problem with how I am using them. The PowerEx is admittedly a little expense to pay for a single battery, but it's working great, seems to have a long battery life, and is both convenient and ecologically superior to going through piles of disposable 9V's.

High capacity, low self discharge

Posted by D.H. on 3rd Jan 2019

I love the powerex brand for high-quality rechargeable batteries with what is usually the highest available capacity in their category, the least amount of self discharge.
